An interesting thing that we have found about the one in RVs might apply in your case from looking at the weather. As the thermostat for cooling is located inside the refrigerator, if the temperature is below about 30 degrees, it will not run and cool the freezer. Just the way it is. If your current temps are below, just turn the heat on inside the RV, leave the refrig door open until it warms up. Then it will probably run OK. To get ours going this year with the temps down around 30 or so, I actually left the door open, and let my electric heater blow into the fridge for a while. Inside temp got up to 50, freezer was beginning to cool OK, so I turned off heater and shut the door. It was back down to about 35 shortly and freezer was below zero.
